15.2.43 Axial distances
$AA_DTBW
REAL $AA_DTBW[X]
axial path from start of block in the workpiece coordinate system for
positioning and synchronized axes for motion synchronized action
The programmed position is decisive for computing the path; if the
axis is a coupling axis, the position part that results from axis
coupling is not considered here.
This variable can only be accessed from synchronized actions
Axes: Channel axis
RS R 2
$AA_DTBB
REAL $AA_DTBB[X]
Axial distance from start of block in basic coordinate system
for positioning and synchronized axes with motion-synchronized
actions
The programmed position is decisive for computing the path; if the
axis is a coupling axis, the position part that results from axis
coupling is not considered here.
This variable can only be accessed from synchronized actions
Axes: Channel axis
RS R 2
$AA_DTEW
REAL $AA_DTEW[X]
Axial distance to end of block in workpiece coordinate system
for positioning and synchronized axes with motion-synchronized
actions
The programmed position is decisive for computing the path; if the
axis is a coupling axis, the position part that results from axis
coupling is not considered here.
This variable can only be accessed from synchronized actions
Axes: Channel axis
